Eighty-four people have died and dozens more are injured after a lorry mowed down crowds at Nice’s Bastille Day celebrations.

The world is mourning the apparent terrorist attack which rocked France for a third time late on Thursday.

No-one has yet announced responsibility for the attack, but President Francois Hollande has claimed it had “an undeniable terrorist nature”.

The tragedy follows the Charlie Hebdo shootings in January 2015, and the atrocities last November which left 130 dead.

France remains a popular tourist destination, with 17 million of us Brits choosing the country for our travels.

So if you or someone you know is visiting our neighbours soon, here is some advice for staying safe.

How likely is it that there will be a terrorist attack while I am there?

There is currently a high risk from terrorism in France, with a state of emergency extended for three months.

The French Government has advised people to be especially vigilant while out and about, and has reinforced its security measures.

However, many Brits travel to France every year, with trouble-free visits. According to the Foreign Office, the biggest threat to tourists is pick-pocketing.

France is believed to have some of the best security in the world. Tourist locations, such as the Notre Dame and the Eiffel Tower, have been especially reinforced with police and military patrols.

If I am involved in a terrorist attack, what should I do?

The French Government advises that people need to ‘escape, hide, alert’.

The official campaign says to escape from the incident as quickly as possible, avoiding exposing yourself through windows and over walls, and staying away from the place of danger. Help others on your way out, and warn those moving into the area.

If it’s not possible to escape, hide by locking yourself in a room or barricading the entrance. Move away from windows, hide behind solid walls, mute all devices and turn off lights.

Alert the local authorities about the incident as soon as you are safe. The emergency number in France is 112.

When approaching police during an attack, make no sudden movements and keep your hands open and in the air.

Always follow the advice and instructions of the French authorities.

Okay, so how can I best prepare for my safety before an attack?

Stay vigilant. This means locating emergency exits when you enter a venue, and reporting any suspicious activity or behaviour to the security forces, on 17 or 112.

The French Government has created a free app to alert savvy users against all possible security risks. This includes natural disasters, technological threats and potential terrorist attacks.

The app, called SAIP (Système d’alerte et d’information des populations), is available in both English and French, and will cover eight geographical locations in France.

Search ‘SAIP’ in the Apple app store or Google Play.

Where are the riskiest areas in France?

The whole of France is on a high level risk of terrorism, but it is believed tourist destinations will be a particular target for indiscriminate attacks. This includes Paris, transport hubs and areas where there will be large crowds.

Corsica, the French Mediterranean island, has also been a target for explosions and attacks on holiday homes, restaurants, Government buildings and police vehicles. This is believed to be due to the Corsican nationalist group FLNC.

Why is France a terrorist target?

Unfortunately, most of Europe, including the UK, is currently on alert.

However, France has been labelled as the central location for terrorist attacks in Europe, as it is thought to be a beacon of Western philosophy, equality and liberty.

French military interaction against Daesh has also triggered a backlash by the radical group, with ongoing threats to France.

In a video in September 2014, Islamic State called the French in particular “spiteful and filthy”.

The Foreign Office pleads that all British tourists and nationals remain vigilant.

I’m booked to go to France, but I’m not sure if I want to go now. What can I do?

If your flight gets cancelled, then you are entitled to a refund.

However, if you want to cancel your ticket, you will probably not get a refund.

There is no FCO warning not to travel to France, so travel companies will be operating as usual, and cancellations will be treated as such.

And what about flights from Newcastle?

If you’re flying out to Nice on easyJet this weekend, you can change the date or destination of your flight without being charged. All easyJet flights will continue to be to schedule.

Contact your travel agent or travel company for advice on whether it will be possible to cancel on other flight operators or trains.
